摘要: 对于前人提出但未被重视的绘制-检出栅格化方法进行了阐述,给出了其实现步骤与关键语句,并赋予其一个新的名称——基于绘制-检出的矢量数据栅格化方法。对该方法实现中的一些技术问题,如正确性、精度、内存位图大小限制、分块栅格化、栅格化效率等问题进行了深入的探讨。笔者认为,该方法可以成为一种普适的工业方法。

Abstract: This paper presents a public and light interpretation to an old method,and uses a new name—rendering and pickup,proposes the procedure detail and key sentences about the method implementation,discusses some techniques deeply about the method in correctness,precision,limited for memory bitmap,partition rasterization and time-spend.The authors think that the old method could become a generally industrial method.
